tance which is twice as great as the object moved by the thread on the opposite end oi' the shaft. On the left handend of the beam and copcrating with the threads of the shaft is a sliding balance Weight K, and on f number of articles of similar 'Weight placed inthe counterpoise Weight receiver The result is that the number of computations and the multiple capacity oi the scale is only limited by the size and strength ci the arts but a convenient arranrenient 7 that shown inthe drawings, wherein the longitudinal graduations withL 'which .the edge Z registers idicate one unit the lirst or top row of computations extending longitudinally of the beam, ive units in the second row' or computations and ten. units in the bottom row of computations, For example, it one nut or bolt be placed in the counter-poise Weight receiveri, the position of the indicator i will slf'levv the number of similar articles which placed on the platform' or goods receiver to balance the scale. li the pointer Z stands in the position shown in the dravi. "s, and the scale is in balance, 2G() of the articles will be found cn 'the platormor goods receiver. blve of the articles are placed in the counterbalance Weight receiver L", the second row el computations is read, and in the position of the pointer shown in the drawings, l,000 ci such articles will be on the platform when the scale is inbalance. If ten of the articles are placed in the counterpoise Weight receiver L, the bottom row of computations is read, and in the position indicated 2,000 or the articleswvill be on the platform when the scale is in. balancea The adjustment oi the carriage L is effectcd by the handle z', and such adjustnient automatically moves the balance Weight K toward or from the axis of the beam in exact accord with, but in an op posite direction from the movement of the carriage. The weight ot the carriage and parts thereon and of the balance Weight K, it will be understood, are so related that the movement does not atleet the balance ol the beam, and therefore the weight ot' the articles, placed in the counterbalance receiver L is the true coun'iterbalanein@l weight.

In order to increase the capacity of the l until the beam is in balance.

2 rilassa scale Without complicatie/n, it is preferred to provide it with means whereby a delnite number of articles may be weighed out or segregated Without the necessity of any adjustment, and for this purpose the intermediate lever B2 is provided with apendent goods receiver N supported on lnii'e edges n on the lever, and the position of the knife edges n with relation to the axis of the lever is such that the desired number.` 0f 75 articles placed. in the goods receiver N Will be counterbalanced by a single one of the articles placed on the counterpoise bala/nce cup E. For example, in the scale shown, a single article placed on the counter-poise' o balance cup E will exactly balance lfill arti cles placed in the goods receiver N, thus providing a convenient arrangement for weighing; out or counting articles by the gross. llhile the supplemental goods reg5; ceivcr ll may, 11.,.bovc indicated, be positioned yat any point on the intermediate lever, its position remains fixed, as does also theposition of tl e countcrpoise balbe established and fixed during the construction of the scale.

Qoviously the scale may be used. either to deteiiinine the number' of articles in a Igiven bulli: or counting out a desired number of articles -ironi a bullrn In the fir t instance, the articles, the nur ber el which is to determined, placed on the platform or load receiver, and one, .tive or, tenor such articles, as 'the case may be, 10U placed in the ccunterpoise weight rece v'er L. 'ily 'means of the handle the carriage is then moved until thelbemn is inbal ance ano the indica* r Z will show at once Ithe number oL rt-icl'es on the olatliorm. llo .les

count out a c., i number; of articles, the carriage is first adjusted to the desired indication a d then., one, five or ten ci" the articles, as c' case may be, placed in the counterbalance receiver L. 'lhen articles 110 are placed on the platform until the beam is in balanceu The scale is particularly effective and useful in countin out all small articles of uni-- torni Weight, such, for instance, as nuts, H5 bolts, Washers, screws and other commodities which are sold by number rather than by Weight. By combining the counting with the Weighing beam the usefulness oi: the scale is extended, inasmuch as it may be used primarily as a weighing scale or as a counting'seale, or for first determin ing the .veight and then counting the nurnber of articles For example, a number of articles may be counted out, and then the weight determined, `without altering any adjustn'ient further than to remove the Il ccunterbalancing articles from the receiver la and advancing the weighing poise F ance cup E, and the relation must therefore m' weight indicating counterpoise a 'bai' graduated in multiples Having thus described my invention, what I Claim es new and desire to secure by Le*- ,ersPatent of the United States, is:

A counting and weighing saaie cemprising a platform, a draft red extending up Wal-diy from said platform, an intermediate lever te' which said draft-rod is pivotally connected, a pivoted beam, e link connecting` said pivoted beam and intermediate lever, the pivotal axis of the beam and link connection being fixed with ieietion to each other, and said beam embodying a. bar graduated to indicate Weight, a sliding on said bai7 of ari-idee to be counted, a carriage mevabiy mounted on the beam to register with she last named lgraduations, e. zeceiveiy for articles to be lexf'er.
